Start by preping all ingredients.
Stick one straw into each marshmalllow almost up to the top. Select the marshmallows with better shapes or simply reshape them gently with your hands and fingers. Melt about 1 cup of the green candy melts in a tall microwavable glass according to the package directions (about 1 minute total, in 30-second intervals, or until melted and smooth when stirred).
You may repeat the melting process with another 1 cup of green candy melts in a separate glass in order to finish covering all the marshmallows. Dip each marshmallow into the melted green chocolate (use a spoon to help coverage, if necessary); then remove excess by scraping gently and smoothing over with a small offset spatula, plastic stick, or the dull side of a table knife.
Stick them firmly, straw side down, in a bowl full of rice or pebbles in order to let chocolate dry.
Melt about 3/4 cup of the brown candy melts according to the package directions. Dip the tops of the marshmallows into the brown candy melts and then sprinkle the chocolate sprinkles on top of the area of molten brown candy melts in order to form the "hair." Stick straw side down in the bowl again and let dry.
Use a toothpick to place a small amount of the molten brown candy melts on the back of the eyes and "glue" in place on the front of the dry marshmallows.
Place a little bit of the molten brown candy melts onto each Rolo chocolate and "glue" them onto the sides of the dry marshmallows. You may need to hold each one for about 10 seconds to make sure they stay in place.
Cut open the tube of black gel and draw a mouth and stitches on each marshmallow. Let set. Inactive time: About 15 minutes
